This paper presents a new experimental method to measure the principal axes of a rigid body without the principal axis transformation. A rigid body is suspended from a vertical axle by a slender rod. The axle rotates with a constant angular velocity. The experimental results for a cylinder and...

tau starts and accumulates in a heterogeneous manner across different regions in various individuals. In this regard, it is imperative to consider that the different networks being progressively affected by AD pathology may be largely determined by underlying macro-scale axes of cortical organization in...
Let's assume that we have a flat object which has a random shape and does not have a symmetry axis. Let's assume the flat object lays in the xy-plane. Any rigid body in principle has a set of three principal axes, which can be found generally by diagonalizing the matrix corresponding...
The initial rotation is such that the final stretch is accomplished without any change of direction in the principal axes of the ellipsoid; seeFigure 3.8. Note that R is a rigid rotation of the small neighborhood of X, not of the body as a whole; R can be a function of position, so ...
In the last case, the inertia tensor is still hermitian, and is the identity matrix multiplied by a vector rather than a scalar. My question is; how do I properly discuss the differences in "flavors" of principal axes? These all are principal axes, correct? Since The angular velocit...
